Elastic -vs- Inelastic Collisisons

Elastic Collisions: Conserve P and E

Inelastic : Only Conserve P

Definition of Momentum Transfer

4-Momentum vector definition using Ryder convention

[math]P_{\mu} equiv \left ( \frac{E}{c} , - \vec p \right )[/math]

[math]P^{\mu} equiv \left ( \frac{E}{c} , \vec p \right )[/math]

[math]P_{\mu} P^{\mu} = \left ( \frac{E}{c}\right )^2 - \vec p^2 = E^2-p^2 = m^2[/math]
